Improve gas pressure.Gas temperature also accordingly improves simultaneously.By multistage-combination, it is possibility to have intercooled multistage combination,
Even multi-cylinder combination compression obtains the required final pressure of gas.
The arrangement of multistage axial flow compressor is generally one-part form plural serial stage structure, and compressor passes through two sets of shaft couplings
It is connected with a jackshaft with a motor, the operating of compressor drum is driven by a motor.The characteristics of this arrangement
It is：Power needed for driving compressor is provided by a motor, and the machine operation and torque of compressor are transmitted by a set of two associating
Axis device and an intermediate bearing by.In ultra-large type multistage axial flow compressor, if by motor, shaft coupling, jackshaft processing system
Horizontal limitation is made, long an axis and heavy-duty motor are difficult to realize in the size of manufacture and craft precision, Wu Fajia
Work.The motor of the power level of the current country more than 80MW there is no operation case, in the case where rotating speed is relatively low, the shaft coupling of shafting
Device, intermediate shaft size are big, and design and processing and manufacturing difficulty are larger, need to realize plural serial stage operation using novel frame mode
Function.
Invention content
The technical problem to be solved by the utility model is to provide a kind of ultra-large type two-part multistage axial flow compressors to pass through

Vertically, the motor described in two is separately positioned on the both ends of casing, and the impeller described in level Four is divided into two groups and is arranged in casing, and two
Platform motor is respectively individually by jackshaft and shaft coupling one group of impeller of series connection, and on the same axis, impeller is by bearing for all impellers
Case supports, and the impeller quantity difference in two groups of impellers is no more than.
The impeller shares level Four, is respectively by taking level Four as an example：One stage impeller, sencond stage impeller, three-level impeller and level Four leaf
Wheel, the one stage impeller and sencond stage impeller are connected for one group with the motor of air duct inlet side, the three-level impeller and level Four impeller
It connects for one group with the motor of ducting outlet side.
Hydraulic cylinder is additionally provided in the casing, the Driven by Hydraulic Cylinder connects the recliner of impeller to adjust the angle of impeller
Degree.
The bearing housing altogether there are two, be separately positioned on one stage impeller and sencond stage impeller, three-level impeller and level Four impeller it
Between.
The utility model ultra-large type two-part multistage axial flow compressor is for heavy-duty motor, big torque clutch, centre
Axis etc. there is no the situation of processing and manufacturing ability, be divided shafting with the arrangement of two-part by the air duct cooperation of rational design
It it is two sections, every section of shafting is driven respectively by a motor so that power of motor, the torque of shaft coupling transmission, intermediate shaft diameter are all
It can greatly reduce, reduce design and processing and manufacturing cost, the design to realize ultra-large type multistage axial flow compressor provides
A kind of high structure layout pattern of reliability.
